Is this normal

Angelina

I am 23 weeks pregnant with my first child and I have been experiencing dryness and itchiness down there. My doctor tested me for stds and stis but it came back negative for everything however she said I had a vaginal bacterial infection and gave me medication to treat it. I did I followed the instructions and completed the treatment and that helped with odor. That was about 2 weeks ago. But for the past couple days my vagina has been irritated, dry and itchy I’m not sure what’s going on and I don’t it to be something that effects my baby. Please let me know, thank you.
